I have a bar chart made with TeeChart. I have on click events on the series which are not activating with most clicks. It seems to depend on the exact spot the cursor is pointed at. The bars are small but it should work. I've not had this problem before and I have had many versions of TeeChart on different versions of C++ Builder. Earlier versions of my software are still working. I can't use the Steema forums without being a customer. Fraser.
